Ingerophrynus is a genus of true toads with 12 species. These species distributed in southern Yunnan and Indochina; peninsular Thailand and Malaya to Sumatra, Borneo, Java, Nias Island, Sulawesi, and the Philippines. This genus was established after a major taxonomical revision of frogs. Ten of the species in this genus were formerly considered species of the genus Bufo. In 2007 a new species, Ingerophrynus gollum, was added to this genus. This species is named after the character Gollum created by J. R. R. Tolkien.
